There are many scholarly works on hongaku thought in medieval Tendai, but how important is it for contemporary Tendai?

In his article "Critique of Original Awakening Thought in Shôshin and Dôgen" Tamura Yoshirô writes:

Later on, the affirmation of Original Awakeningthought was abused to the point that, at the end of theMiddle Ages, things like the Altar Society of Refuge inMystic Lore (Genshikimyôdan) originated with the intentionof praying for the fulfillment of one’s worldly cravings forsensual gratification and possession. Against these abuses,Myôryû Jizan (1637-1690) and Reikû Kôken (1652-1739)—thelatter especially in his Byakujahen (Chapters of RefutingUnorthodoxy; text preserved at Otani and Taishô Universities)of 1868—unleashed vigorous attacks. This, it is said,signaled the end of Original Awakening thought.

This could make you think, that hongaku thought is not significant anymore, but the text continues:

However, these people directed their critique against that one particularmanifestation of Original Awakening thought, withoutrejecting it as a philosophy.

Does this mean, that it is still important for contemporary Tendai as a philosophy?
